Reflected XSS via unescaped login error
Published Nov 3, 2025 · Updated Nov 3, 2025
Reflected XSS in School Management System PHP 1.0 allows remote attackers to execute script in a victim's browser via login.php. The login.php handler writes the error query parameter into the HTML response without output encoding, so injected script markup is interpreted by the browser. A victim must open an attacker-crafted URL; successful exploitation runs script in that application origin, enabling session-cookie access or page-content changes.
